A pillow block bearing is typically used in applications that support light industrial loads. With a bearing housed in a mounting bracket to support a rotating shaft and couplings, pillow block bearing units facilitate mechanical power transmission. The bolted support surface helps the inner ring and shaft to rotate freely.

A pillow block bearing is sometimes called a plummer block bearing unit, for both are similarly constructed. Nevertheless, they are used for different applications. When a bearing pillow block is meant for light industrial loads, a plummer block bearing is used for heavy loads by transferring high power.

With a pillow block bearing unit, you can have the shaft rotating smoothly with a compatible bearing and ring raceways. The bearing’s inner part holds the shaft tightly, while the collars and screws secure it.

Using this housed bearing unit, you can find an anti-friction bearing mounted in it, which keeps your machine parts safe. Further, the shaft is mounted parallel to the support surface and vertical to the mounting screws, which helps secure it. A pillow block bearing unit uses any type of bearing like ball bearings or roller bearings. With roller bearings, you can find a few popular types like cylindrical, spherical, and tapered roller bearings.

How to Choose the Best Bearing Pillow Block Design?

To have an appropriate pillow block bearing design much depends on the type of bearing used. For instance, you need to consider the running speed, shaft size, type of load to handle, and misalignment. Henceforth, for selecting the most suitable plummer block bearing unit, you need to first choose an appropriate bearing and ring washers.

You can choose a bearing from the plain, ball, and roller bearings depending on your requirement. Nonetheless, you can ensure high operational reliability by selecting roller bearings due to the logarithmic profiles of the rollers, which help form a hydrodynamic lubricant film for smooth rotational movement.

The bearing is safely mounted in the design with a stable outer ring and rotating inner ring. The bolted foundation keeps the bearing unit safe while in operation. You can find block pillow bearing designs in two types - split type and solid type. A split type has a removable cap or housing element and the base. The solid type is a single piece of housing.

Get to Know the Design Variants of Pillow Block Bearing Housings

The bearing unit with small changes in design and helps meet the requirements of some applications. For instance, you can use pressed steel bearing housing unit made from chromium-free steel with zinc coating suitable for low-speed applications. If you are looking for an anti-corrosion bearing with a lubrication system, you can choose a cast iron bearing housing unit.

The information provided will help you choose to find the best bearing pillow block unit for your industrial application.
